It's about one-four-hundred-fiftieth as fast as a Knuckleball (baseball).

In other words, the speed of a Knuckleball (baseball) is 450 times 240 meters per hour.

(a.k.a. knuckler, a.k.a. floater, a.k.a. dancer, a.k.a. butterfly ball) (major league average)The average speed of major league knuckleball pitch is 110,000 meters per hour. Eddie Cicotte, who was later implicated in the 1919 Black Sox scandal, is credited with developing the pitch ca. 1906.

In other words, the speed of a Curveball (baseball) is 500 times 240 meters per hour.

(a.k.a. hook, a.k.a. hammer, a.k.a. yakker) (major league average)The average speed of major league curveball pitch is 120,000 meters per hour. In the 1940's, debate over whether there really was a curve in the curveball pitch was settled with the conclusion that the ball does curve; however, an optical illusion caused by the spin of the ball and the batter's perception of motion exaggerates the extent of the curve.

In other words, the speed of a Fastball (baseball) is 630 times 240 meters per hour.

(a.k.a. rising fastball, a.k.a. cross-seam fastball, a.k.a. heater, a.k.a. hummer, a.k.a. smoker; for four-seam grip) (major league average)The average speed of major league fastball pitch is 150,000 meters per hour. When up against the quickest professional fastball pitchers, a batter may have less than 0.4 seconds to react to a pitched ball.

It's about one-seven-hundred-fiftieth as fast as a Skydiver (belly-to-earth).

In other words, the speed of a Skydiver (belly-to-earth) is 770 times 240 meters per hour.

(Belly-to-Earth orientation, average conditions, terminal velocity)A belly-to-Earth oriented skydiver's terminal velocity is about 190,000 meters per hour. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.

In other words, 240 meters per hour is 0.001207523 times the speed of a Tornado, and the speed of a Tornado is 828.1416 times that amount.

(EF2) (wind speed range average)According to the Enhanced Fujita scale implemented by the US National Oceanographic and Atmospheric Administration, a "significant" tornado has an Enhanced Funjita scale classification of EF2 and is characterized by wind gust speeds between 177,027.8 meters per hour and 220,480.1 meters per hour. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
